Looking for transmission info

Recommended Posts

Hi all,

New to the forum. Thanks for having me.

I'm currently working replacing the transmission on a 2003 Silverado 4.8L 4X4.

The transmission that came out of has part # 24217284

The transmission I have to install is part # 24242420

I can't seem to find any info on that part #. 

It looks like it should fit, but will it work?

Thanks in advance!

What did the donor transmission come out of? I usually use car-part.com to verify that my used parts are compatible. I'm not an expert, or even really knowledgeable but from what I have heard and have read about 4l60, only a couple of rules apply.

1)Don't use a v6 one in a v8 application. 2)Make sure you get  the right one for 4wd or 2wd depending on what you need. Changing the output shaft requires a bunch of disassembly. 

3)If you vehicle needs the iss, make sure your trans has that. It's OK to have it not use it, but can't not have it and need it. 

4)make sure you have the correct input shaft 300mm vs 298mm.
